Ok so last night I spent hours slicing up a hi hat loop to get it to sync with my project as the timing was a little looser than I would have liked and fairly inconsistent. I had it pretty much perfect, bounced it to soundcloud etc all was good.

Now today I load up the same project, haven't touched it at all and all the timing of the slices is out. I can't for the life of me find out how this happened.

Anyone have any ideas? I've tried loading project backups and it's the same thing. Timing was all perfect before.
